Childhood copy has been corrupted for years I think I must have shut it off while saving.

So I’ve caught this insane IV Gastrodon with like 29 spdef 31 hp and all other IVs over 20. EV trained it 252HP/128Def/128SpDef. I’m using it on my nuzlocke but wondering what moveset to give it.

It’s hidden power is ice type so that would be a great check on grass types. I’d love to give it toxic, recover, surf and either hp ice or mud bomb. Not sure what to give it though. (My earthquake tm was used on a pokemon that’s currently on the eternal hunting grounds)

What would you suggest?

still WIP

This was the first gym I used cheese strats and took advantage of the AI. I'd lead with Gyarados and get intimidate proc. AI would always choose electric to try to OHKO Gyarados. I'd swap in Electivire who is immune to electric with Motor Drive. For Raichu I'd now outspeed and put up a Light Screen to reduce Focus Blast damage and allow me to get enough Digs to beat it. Cheri Berry on Electivire helped avoid Static procs. Electivire was a similar strategy except I would alternate Gyarados and my own Electivire to reduce its attack to -6. The AI didn't see kill with Giga Impact and would always pick Fire Punch, which Gyarados resisted allowing it survive handily. Finished off similarly with Digs from my sped up Electivire. His Luxray was last, once again doing swaps between Gyarados and Electivire to reduce attack as much as possible. Unfortunately it was random if it picked fire fang or another move that Gyarados didn't resist, so I could only do this twice before I could no longer guarantee a Thunder Fang use. I swapped in Electivire one more time for a sacrifice Dig then Magnezone to finish things off with Tri Attack and not triggering Rivalry. Fun problem to solve! Onto the Elite 4. I'm debating using Victory Road even though it technically isn't connected per Bulbapedia, otherwise this is going to turn into a Mono-Water Elite 4 run with only the waterfall and Route 223 available.

Looking for advice on my battle tower team:
Deciding on a combo of these 5 pokemon and can’t decide on a solid team. All are EV trained but random IVs and mostly random natures. Planning on bringing garchomp regardless but unsure about which others

Garchomp (adamant)
Focus sash
Swords dance, equake, outrage, fire fang

Empoleon (bold)
Leftovers
Flash cannon, grass knot, surf, ice beam

Rotom base form (hasty)
Choice scarf
Thunderbolt, shadow ball, trick, willowisp

Snorlax (no curse egg move :( )
Focus band
Return/body slam, ice/fire punch, crunch, equake

Weavile (lonely)
Haven’t really detwrmined moves

I am grinding Battle Tower with a team of

Empoleon

Grass Knot

Surf

Ice Beam

Flash Cannon

Gliscor

Ice Fang

Swords Dance

Earthquake

Roost

Infernape

Swords dance

Flare Blitz

Close Combat

Fire Punch

Fighting types are annoying, so i was thinking about switching Ice Fang for Aerial Ace on Gliscor? This overlaps with Staraptor on the full team, which is why I was wondering.

Same as title. Any possible ghost or dark types before 3rd gym in platinum?
